Your MCP23017 is alive, so if you:

- changed the port in zyncoder source code + re-build
- connected the encoders in the right way
- choose the right configuration in webconf

It should work 😉

I suppose you are using this info:

> OK! I’ve a zynaptik with all the parts soldered on it: The second 40-pin connector is the “zynaptik connector” and has this pin-out: Where: GPAx & GPBx are digital input/output pins (MCP23017, at I2C address 0x21) INTA & INTB are interrupt pins for banks GPAx & GPBx, connected to RBPi pins 36 & 37. AD-x are analog input pins (ADS1115) DA-x are analog output pins (MCP4728) I will copy this info to the wiki ASAP wink Regards,
